Phase noise is the term used to describe measurements of the short-term fre-quency stability of these sources. This white paper provides a brief technical introduction to phase noise concepts as well as an overview of how phase noise is measured and reported.
Phase noise is defined as the ratio of the noise in a 1-Hz bandwidth at a specified frequency offset, fm, to the oscillator signal amplitude at frequency fO. The sampling process is basically a multiplication of the sampling clock and the analog input signal.
when jitter and phase noise occur, their relationship with one another, how they can degrade circuit performance, and how to mitigate their effects – all in the context of the most recent research in the field.

Complying to the usual terminology, we use the symbol for the frequency and f for the Fourier frequency, i.e. the frequency of the detected signal when the sidebands around are down converted to baseband. The power-law model is most frequently used for describing phase noise.
